An opal is a hydrated form of silica with a water content ranging from 3 to 21%. Indeed, it is this permeability to water that makes it a hydrophile.
オパールは水分含有量が3%から21%の水和型珪酸塩です。実際、それだけ水に対する透過性があることが、オパールを親水性にしています。
Opals are deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. Only precious opals show a variable interplay of internal colors.
オパールは比較的低温で沈着し、ほぼすべての岩石の割れ目に生じ得ます。特にリモナイト、砂岩、流紋岩、泥灰岩、玄武岩などと共存して見られることが多いです。宝石級オパールだけが内部色の多様な干渉を見せます。
At microscopic scales, precious opal is composed of silica spheres some 150 to 300 nm in diameter in a hexagonal or cubic close-packed lattice. These ordered silica spheres produce the internal colors by causing the interference and diffraction of light passing through the microstructure of the opal.
顕微鏡レベルでは、宝石級オパールは直径約150〜300 nmのシリカ球が六方最密充填(六方最密構造)または立方最密構造を成しており、それらの規則的なシリカ球がオパールの内部色を生み出します。光がオパールの微細構造を通過する際の干渉と回折を起こすことによって内部色が生じます。
